Lixesenatide and lantus

I have just completed a trial program where i took lixisenatide and lantus in one pen. Lixisenatide is a glp 1 agonist just like byetta or victoza or bydureon. My aic went down to 5.1 from over 8.To me the conclusion i have drawn is that combining a long acting insulin with a glp1 agonist is much more effective than just a long acting insulin. I suspect it can help delay the need for humilin or other faster acting insulins that may be needed before meals.
Lixisenatide has been approved in Europe and this increased my comfort level in taking it.
